  • Research summary

    The purpose of this study is to see how well and how safely a study drug (called ‘JNJ-56136379’) works in people who have hepatitis B. The study drug will be compared to a dummy drug (or ‘placebo’). This study will look at the effects of JNJ-56136379 alone and in combination with either of two drugs already approved to treat hepatitis B: entecavir (ETV) and tenofovir disoproxil fumarate (TDF). All treatments are tablets to be taken once a day. This study is made up of an 8-week screening period, a 24-week treatment period and a 24-week follow up period. At screening, participants sign an informed consent form then they undergo various tests and assessments to see if they can enter the study. These include blood tests, an electrocardiogram and procedures to look at the liver (if a participant has not had these done recently). If a participant is eligible for treatment, it will then be decided by chance which treatment they receive: JNJ-56136379 or placebo. If a participant has never received treatment for their hepatitis B (or not in the past 6 months), it will be decided by chance which of the following three treatments they will receive: JNJ-56136379 alone, JNJ-56136379 plus ETV or TDF or placebo plus ETV or TDF. There is a 6 in 7 chance that a participant will receive JNJ-56136379. If a participant is already taking ETV or TDF for their hepatitis B, they will continue to take that medicine, but will also receive either JNJ-56136379 or placebo. There is a 3 in 4 chance that they will receive JNJ-56136379. During the treatment and follow-up periods, participants will be asked to come to clinic for further tests and assessments. Participants will be continually monitored and their JNJ-56136379/placebo stopped if they are unable to tolerate any side effects.
